The journey with rutherford and the atom
Previously, before Niels had made his contribution to the atomic structure, Earnest Rutherford and many other scientists had already picked out some key parts in the atom's anatomy. Earnest proposed that positive charge came from within the nucleus, this proven by his "Gold Foil"'experiment. Eventually Niels arose with a new theory that complimented Earnest’s work. He had begun studying under the guidance of Earnest himself, after studying under J.J Thompson, who did not necessarily agree or encourage Niels ideas, at Manchester's Victoria University. Refining the model that scientists had collaboratively discovered, in 1913 Bohr hypothetically suggested that the electrons are in comparison with the planets that orbit the sun, implying that the electrons systematically orbit the nucleus in shells. This also meaning that it contains a certain amount of electrons per orbit-therefore the explanation of the periodic table's structure and format. As well as discovering the orbit, he realised that when an atom jumps from one orbit (shell) to another, lower energy to higher energy, it radiates light. The emission of light was discovered when Bohr used a spectrometer to measure the wavelengths of light.
How? You may ask how is it possible for the electrons to be able to orbit systematically around the nucleus of the atom. Well, the nucleus is positive and the electrons are negative, this simple relationship creates an attraction in which positions the electrons in a particular orbit, however, depending on the quantity of energy - this will determine its orbit.

Quantum theory

Quantum theory is a theory collaboratively researched and questioned by Niels Bohr, Erwin Schrödinger, Wolfgang Pauli, and Max Born in relevance to Einstein’s relativity theory in the beginning of the 20th century. Quantum theory involves the most microscopic particles on our planet, these are what create atoms, in which are 'subatomic'. Niels became aware of the amounts of quanta, which is where the quantum theory is introduced to the atomic structure.
